Nigerian Vegetable Pasta with Uziza, Ugu and Groundnut Oil

How to Make It

1. 1

   Prepare the Pasta

   Bring a large pot of lightly salted water to a rolling boil. Add the whole wheat spaghetti and cook according to packet instructions until al dente — typically 8 to 10 minutes. Al dente pasta has a lower glycaemic index than fully soft-cooked pasta, which supports better post-meal blood sugar control. Drain and rinse briefly under cool water to halt cooking. Drizzle with a few drops of groundnut oil to prevent sticking and set aside.

   Tip: Reserve approximately 100 ml of the pasta cooking water before draining — its starchy content can be used to adjust sauce consistency later without added fat or salt.

   Prepare the Vegetables

   Wash all fresh produce thoroughly under cold running water. Shred ugu leaves roughly, discarding tough stalks. Thinly slice the uziza leaves and set aside separately, as they will be added at the final stage. Quarter the garden eggs, slice the red and green bell peppers into thin strips, finely dice the red onion, and roughly chop the plum tomatoes. Mince the garlic and grate the fresh ginger.

   Tip: Soaking quartered garden eggs in lightly salted water for 5 minutes before cooking draws out some of the natural bitterness while preserving their texture and soluble fibre content.

   Sauté the Aromatics

   Heat the cold-pressed groundnut oil in a large, wide-based pan or wok over medium heat — avoid high heat to preserve the oil's beneficial unsaturated fatty acid profile. Once shimmering, add the sliced red onion and cook gently for 3 to 4 minutes until softened and translucent. Add the minced garlic, grated ginger, and ground turmeric, stirring continuously for 60 seconds until fragrant. This low-heat aromatic base maximises the bioavailability of fat-soluble curcumin from the turmeric.

   Tip: Combining turmeric with black pepper increases curcumin absorption by up to 2,000% — add a pinch of freshly ground black pepper to the aromatics at this stage.

   Build the Vegetable Base

   Add the chopped plum tomatoes and minced scotch bonnet pepper to the pan. Stir well and cook for 4 to 5 minutes until the tomatoes begin to break down and the mixture becomes fragrant and slightly jammy. Add the garden egg quarters and bell pepper strips, stirring to coat evenly in the tomato and oil base. Pour in the low-sodium vegetable stock and allow everything to simmer gently for 6 to 8 minutes until the garden eggs are just tender but still holding their shape. Add the ground crayfish (if using) and ground uziza seeds, stirring to incorporate.

   Tip: Avoid over-softening the garden eggs — their slight firmness contributes textural contrast and preserves their soluble fibre, which is beneficial for gut health and blood sugar regulation.
5. 5

   Wilt the Greens

   Add the shredded ugu leaves to the pan and fold them gently into the vegetable mixture. Cook for 2 to 3 minutes only — ugu wilts quickly and prolonged heat degrades its iron, folate, and vitamin C content. Season carefully with sea salt or potassium salt blend and freshly ground black pepper. Taste and adjust seasoning before adding the pasta.

   Tip: Clinical note: Ugu (Telfairia occidentalis) is an excellent source of non-haem iron and folate. Pairing it with vitamin C-rich sweet peppers in the same dish enhances iron absorption — a clinically meaningful combination for anaemia prevention.

   Combine the Pasta

   Add the drained whole wheat pasta directly to the pan with the vegetable mixture. Using tongs or two large spoons, toss thoroughly to coat every strand evenly in the groundnut oil, tomato base, and vegetable juices. If the mixture appears too dry, add a splash of reserved pasta water, a little at a time, until the pasta is well-coated and glossy. Heat through over a medium-low flame for 2 minutes.

   Tip: Tossing the pasta over residual heat rather than returning to a high flame prevents further starch breakdown, keeping the glycaemic response lower and preserving the integrity of the delicate leafy greens.

   Finish with Uziza and Serve

   Remove the pan from the heat completely before scattering the thinly sliced fresh uziza leaves over the pasta. Fold them in gently — residual heat will wilt them just enough while preserving their distinctive peppery essential oils, which are volatile and diminish rapidly with direct cooking. Divide into four bowls and serve immediately. For a complete clinical meal, pair with a small portion of grilled tofu, eggs, or lean white fish to increase the protein content per serving.

   Tip: Uziza leaves (Piper guineense) contain piperine compounds similar to black pepper, which have demonstrated anti-inflammatory and digestive enzyme-stimulating properties in clinical literature — adding them off-heat maximises these benefits.
